Description
The Idaho Department of Environmental Quality (DEQ) administers State Revolving Fund construction loans to help qualified systems improve drinking water and wastewater facilities. Supported in part by U.S. Environmental Protection Agency funds, the program provides below-market-rate financing for project planning, design, and construction, reducing financing costs over the life of infrastructure projects.
DEQ ranks proposed projects based on public health and environmental concerns, long-term system sustainability, regulatory compliance, and readiness to proceed. Drinking water and wastewater Intended Use Plans identify priority projects for assistance. The program also encourages green infrastructure, water conservation, energy efficiency, environmentally innovative activities, and cyber-informed engineering. All SRF construction projects undergo a state environmental review process.
